When should a student cancel the use of coordinated airspace?

• A. At the end of the hour.
• B. After pilot request.
• C. When it is no longer needed.
• D. Never cancel.

Answer: (C)

Coordinated airspace is a temporary allocation you use only as long as there’s a real need to support a specific flow or sequencing. The best practice is to cancel it as soon as that need ends—when there’s no longer aircraft that require the coordination and the normal airspace can safely handle operations. Waiting until the end of a fixed time or only after a pilot asks can waste capacity or cause unnecessary delays. Similarly, never canceling would keep the space reserved longer than needed, limiting availability for others. So you cancel when it is no longer needed.
